EGYPT: SAUDI KING'S NEPHEW ATTACKS POLICE - FORCED TO LEAVE - Saudi Arabia - ANSAMED.info
ROME, JULY 18 - Egypt's authorities have decided to kick prince Ahmed Turki Ben Abdulaziz, the Saudi King's nephew, out of the country for attacking police officers at Cairo airport a few days ago. Egyptian newspaper 'Al Masry Al Yaum' also noted that the prince's name has been added to the airport's blacklist.
After the prince and his bodyguards attacked the officers, the police arrested him and his ''gorillas'' for 18 hours. The Saudi embassy in Cairo had to step in to have the prince released.

A proposed Saudi counterterrorism law that would give the Interior Ministry sweeping powers and mandate jail sentences for criticizing the king would effectively squelch political dissent, human rights advocates said on Thursday.
The law would allow prisoners to be held without trial, and trials and appeals to be held secretly, Saudi and international rights advocates said. It would also grant the Interior Ministry broad powers including the ability to tap telephones or search houses without permission from the judiciary. - Source
